You know.....the quote you mentioned...that is what exactly remains for Sakura to tell Naruto.
I mean she already did. "You saved Konoha once and now you are trying to save the whole ninja world. You are always left with this unsurmountable tasks to deal with. But this time no matter what you say...you will have help. We are going in together! And not just me, everyone is going to help you."
Something along the lines of....."Naruto you were always abandoned by everyone during our childhood. But you always cared for us and never abandoned us despite having every reason to. You didn't even have parents to care for you. You took care of everything all by yourself. But this time....I want to take care of you and do what I should have done a long time ago."....something like....she basically fills the void of mother and father's love, care and etc. in Naruto's heart!
Bolded: Don't give the other fandom any ideas. XD Next thing you know, the other fandoms start saying that Naruto loves Sakura like a mother.
